Returns the ShardingID used for sharding, default implementation returns this parcel type and GDID. Override to return another sharding key, i.e. a social comment msg may use parent item (that the msg relates to) ID as the shard key so msgs are co-located with related items. Use CompositeShardingID to return multiple values. IMPORTANT!!! ShardingID must return an immutable value, the one that CAN NOT be changed during parcel payload life
